반응 단계

Using analogous reagents and reaction conditions as described in Example 1 above, 1-(4-cyclopropylpyridin-3-yl)imidazolidin-2-one (I-1d: 100 mg, 0.492 mmol) was reacted with 4,6-dichloro-2-methylpyrimidine (80.2 mg, 0.492 mmol), 1,4-dioxane (5 mL), copper iodide (9.3 mg, 0.049 mmol), trans-N,N′-dimethylcyclohexane-1,2-diamine (6.9 mg, 0.049 mmol) and potassium phosphate (313 mg, 1.47 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% methanol in CHCl3) afforded 25 mg of the product (15% yield).
